Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for adjusting mounting data created for mounting electronic components and the like on a board assuming actual mounting operations.

Conventional technology Mounting data for operating an electronic component mounting device to sequentially mount predetermined electronic components at predetermined positions on a circuit board is created by a mounting data creation device provided separately from the electronic component mounting device. It is often done.

As such a mounting data creation device, a visual recognition means such as a television camera is placed above an X-Y table on which a circuit board can be placed, and a scale as shown in FIG. 6 is provided in the recognition field 20. A cursor 21 consisting of a cross line is formed and its center position corresponds to the mounting position, and the X-Y table is moved using the control switch to select an arbitrary electronic component mounting position on the circuit board as shown in FIG. A known configuration is such that the center of the land 22 is aligned with the center of the cursor 21, and the position of the XY table at that time is recorded as mounting position data.

Furthermore, such a mounting data creation device simulates the mounting operation based on the created mounting data to confirm whether the electronic component is actually mounted properly on the board, and also to detect incorrect mounting conditions. It is configured so that the mounting data can be corrected in the case of In this mounting data correction, as shown in FIG. It is configured to read the amount of deviation and manually correct the data.

Furthermore, as a mounting data creation device, one that creates mounting data for a predetermined electronic component mounting device based on data given from a CAD system can also be considered. However, even in the case of mounting data created in this way, it is necessary to check whether it will actually be properly mounted and to adjust the data. Similarly, the mounting operation is simulated to adjust the mounting data.

Problems to be Solved by the Invention However, in the mounting data adjustment method as described above, the mounting data is corrected by detecting the amount of positional deviation of the center of the electronic component to be mounted with respect to the center of the land at the mounting position on the board. However, there is a problem in that it is not possible to directly check the mounting state of the electronic component on the land, and in particular, it is impossible to check and adjust the mounting angle of the electronic component with respect to the land. In addition, the correction of the mounting data is done manually, and there is a problem in that it cannot be adjusted automatically, and the adjustment work requires a lot of time and effort.

In view of the above-mentioned conventional problems, the present invention provides a mounting data adjustment method that can accurately adjust mounting data based on the mounting state of components on the component mounting section of a board, and can automatically correct mounting data. The purpose is to provide

Means for Solving the Problems In order to achieve the above object, the present invention positions the board by regarding the visually recognized position as the mounting position based on the created mounting data, and places the components to be mounted at the visually recognized position.

In addition, the recognition image of the component mounting section is image-processed to calculate the center line and centroid position, and the deviation of the position and angle from the center line and centroid position of the virtual cursor is calculated, and the deviation is calculated. It is also possible to correct the mounting data based on.

The mounting position and mounting angle can be adjusted accurately.
In addition, by correcting the mounting data based on the amount of movement of the cursor, the mounting data can be automatically corrected.

In addition, the position of the component mounting part is automatically recognized based on the deviation from the virtual cursor position data by data recognition of the position of the component mounting part from the center line and centroid calculated by image processing the recognized image of the component mounting part. Implementation data can be adjusted.
